LAMP SUPPORT Filed June 25. 1928 F972 h7g4. @915 /9 W a F lN-VENTOR ATTORNEY Patented June 10, 1930 UNITED STATES PATENT OFFICE RALPH EHBENI'ELD, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR T0 WESTING- HOUSE ELECTRIC & MANUFACTURING COMPANY, .A CORPORATION OF PENNSYL- VANIA LAMP SUPPORT Application filed June 23,

My invention relates to sewing machines and particularly to means for lighting the sewing table immediately under and adjacent to the sewing mechanism.

Sewing machines are usually electrically driven by a motor mounted outside and on the base of the machine. It is very desirable that a light be so provided that the work under the needle and immediately adjacent thereto shall be well lighted. Since electricity is available, by reason of the power utilized in driving the motor, such power may readily be utilized to energize an electric lamp for illuminatin the work. However, the means for mounting electric lamps have not beenaltogether satisfacto in that such mounting means has been cum ersome, complicated and ex ensive in construction.

Therefore, an object of my invention is to provide a single su port for the driving motor and the lamp 0 a sewing machine.

Another object of my invention is to provide a lamp and motor mounting which does not require a change in the sewing-machine structure.

Another object of my invention is to provide a relatively simple, compact and incons icuous lamp support for a sewing machine t at shall permit of a plurality of adjusting movements.

Other objects will be made apparent by the following description, taken in conjunction with the drawings, in which Figure 1 is a rear elevational view of a sewing machine, showing my combined lampand-motor support,

Fig. 2 is a side elevational view of the lamp support,

Fig. 3 is an end elevational view of the lamp support shown in Fig. 2,

Fig. 4 is a front elevational view of a clamp utilized for engaging the lamp structure, and

Fig. 5 is an end elevational view of the clamp.

In practicing my invention, I provide a bracket of substantially L-shape mounted on the base of a sewing machine back of the gooseneck and having a driving motor secured thereto at its lower end and a lamp 1928. Serial No. 287,876.

standard adjustably mounted thereon at its upper end.

Referring more particularly to Fig. 1, the sewing-machine head comprises a base 1 and a head or gooseneck 2. The usual shaft for operating the sewing mechanism 4 is mounted in the gooseneck. The shaft of the driving mechanism extends outside the bend of the gooseneck to receive a hand-wheel 5 and a pulley 6.

My support comprises a substantially L- shaped bracket 7 which is adapted to be so fastened to the horizontal surface of the base that the longer portion projects vertically, with its face substantially parallel to the gooseneck. The shorter portion of the brack et 7 is preferably provided with two or more holes 8 to receive screws, by means of which the bracket is fastened to the base 1. Two other-holes are provided substantially midway of the long upright portion of the brack- The sewing machine motor is provided, with tapped holes which register with the holes in the bracket 7 and two bolts extend through the holes in the bracket and into the tapped holes in the motor. The sewing-machine motor is provided with the usual pul-' ley 9 on the end of its shaft 10, and a resilient belt 11 connects the pulleys 6 and 9.

A vertically elongated slot 12 is provided in the upper end of the bracket 7, for use in attaching and supporting the lamp standard 14'. The lamp standard comprises a socket 15 and a tubular portion 16 upon which is mounted a reflector 17. A long tubular lamp 18 is utilized for lighting the work. The lamp socket is attached to the bracket by means of a clamp 19 which comprises a strip of material bent in such manner as to engage the socket, the two ends of the strip being adapted to overlap each other. is drilled through the two ends of the strip and the socket is secured to the bracket by a bolt 21 extending through holes in the clamp and through the slot in the bracket and secured in position by a thumb nut 22.

An electrical connection for the lamp is made by means of a conductor 23 which is connected to a supply circuit. The clamping An opening I action of the thumb nut causes the clamp to grip the tubular portion 16, whereby the lamp may be held in any desired fixed relation to the bracket. It is apparent that the lamp may be turned about the bolt 21 as a pivot, thus permitting adjustment to any angle with the perpendicular and also that the bolt may be moved up and down in the slot 12 to adjust the position of the entire lamp.

Thus, my device permits of angular adjustment of the lamp in a vertical plane as well as vertical movement in its entirety. The device is simple and inexpensive to manufacture. It consolidates two structures which hitherto have given the motor mounting and lamp mounting of a sewing machine a dis jointed appearance by combining the mountings into one unit which adds rather than detracts from the appearance of the machine. The device is simple and practical and may be readily adjusted so that the work may be fully illuminated.

It is apparent that my invention is subject to modifications. For example, the shape of the support may be considerably changed. Such modifications as may be made by those skilled in the art may be made without departing from the spirit and scope of my invention, as set forth in the appended claims.

I claim as my invention:

1. In a sewing machine having the usual head, stitching mechanism and a driving motor, in combination, a lamp and a single means for supporting both the motor and the lamp comprisin a substantially flat plate to which the motor and lamp are attached and means for fastening the plate to the machine.

2. In a sewing machine having the usual head, stitching mechanism and a driving motor, in combination, an electric lamp and a bracket attached to the machine adjacent the vertical portion of the head for supporting the motor at its lower end and the lamp adjacent to its upper end.

3. In a sewing machine having the usual head, stitching mechanism and a driving motor, in combination. an electric lamp and a bracket located adjacent the vertical portion of the head for supporting the motor and the lamp one above the other in a vertical plane substantially parallel to the plane of the head.

a. In a sewing machine having the usual base, a gooseneck, stitching mechanism and a driving motor, in combination, a lamp, a bracket of substantially L-shape secured to the base, means for mounting the motor on the bracket adjacent to the base and means for pivotally securing the lamp at the upper end of the bracket.

5. In a sewing machine having the usual base, a gooseneck, stitching mechanism and a driving motor, in combination, a lamp, a bracket of substantially L-shape secured to the base and having a vertically extending slot at its upper end, means for securing the motor to the bracket adjacent to the base, and a clamping means for the lamp extending through the slot to permit of vertical movement of the lamp.

In testimony whereof, I have hereunto subscribed my name this 15th day of June, 1928.

RALPH EHRENFELD.
